Coastal regions are considered pivotal for socio-economic activities facing heightened vulnerability to Climate Change (CC). The imperative for CC adaptation in coastal zones is evident and is expected to be intensified, followed by dynamic and iterative adaptation strategies. The OCEANIDS project aims to create user-driven tools and applications, serving mainly as a technological layer for regional authorities and stakeholders, enabling them to establish a more inclusive and resilient pathway leading to a Blue Economy in coastal regions. The project consolidates spatial and non-spatial data into a single-access platform for Climate-Informed Maritime Spatial Planning (CI-MSP), enhancing seascape management. Central to OCEANIDS is the O-DSP Decision Support tool, harmonizing climate data for local adaptation strategies. The project emphasizes inclusivity, driving behavioral change at individual and systemic levels. Through inclusive governance and innovative tools like ephemeral social networks, OCEANIDS empowers communities to accelerate transformative changes toward climate resilience. The platform’s capability to assess hazards and provide recommendations supports not only immediate responses but also aids in formulating long-term strategies for mitigating geological risks associated with changing environmental conditions. In summary, it blends technological solutions with a cultural shift, creating a holistic framework for resilient coastal development.
